Popover

Usage

A3S UI popovers are inline-positioned relative to the .popover wrapper. This differs from shadcn/ui's portalled Base UI implementation, but keeps the markup dependency-free and works with A3S UI's existing dropdown/select positioning model.

Include CSS

Import Tailwind and one full A3S UI style bundle.

@import "tailwindcss";
@import "@a3s-lab/ui/a3s.css";

Or import only the base CSS, Popover component CSS, and one style pack.

@import "tailwindcss";
@import "@a3s-lab/ui/base.css";
@import "@a3s-lab/ui/components/popover.css";
@import "@a3s-lab/ui/styles/a3s.css";

Using CDN or bundler imports? See the Installation page.

Include JavaScript

Copy or serve the full A3S UI JavaScript bundle.

<script src="/assets/js/all.min.js" defer></script>

Or copy or serve the A3S UI runtime and Popover script.

<script src="/assets/js/runtime.min.js" defer></script>
<script src="/assets/js/popover.min.js" defer></script>
